Video signal monitoring when monitoring analog video signal, oscilloscope with hierarchical brightness display is a very useful troubleshooting tool.Subtle variations in signals can distinguish between working video systems and abnormal ones, whereas DSO does not see such signals.
The line rate luminance grading of active video signal shows the relationship between signal amplitude and time is the most basic analog video signal measurement, which can be easily displayed by using the full-line trigger mode on the rising edge of synchronization.The new digital fluorescence oscilloscope is equipped with brightness grading display, and at the same time, the waveform capture rate is very high, which can capture each line signal and display the line rate in a way familiar to engineers similar to the wave monitor (figure 1).
Chromaticity XY display oscilloscope XY display mode gives the relation of one signal to another in the form of a vector display.For example, connect the b-y signal to channel 1, and the r-y signal to channel 2, and you will see the same radial display style as the vector display.DPO has the advantage of intensity grading, showing signal details that are not present on ordinary dsos.
Amplitude measurement on an oscilloscope can be carried out in a variety of ways.For example, to measure the pest-peak of the NSTC pulse signal, simply compare the signal with the IRE video grid line of the TDS5000 oscilloscope.In order to analyze the changes after a period of time, the oscilloscope can also automatically make several measurements and save the measurement statistics.
Time measurement is particularly important for multi-signal analog systems. Small time differences between channels can produce edge effects on image monitors. The most important use of multi-channel oscilloscopes is to display the relative time differences between channels.Unlike analog oscilloscopes, DPO can also automatically take time measurements and store these statistics.
